Key Stage 3
Meaning
A physical change is a reversible change that doesn’t result in new chemicals being formed.
About Physical Changes
There are several physical changes that can happen to materials:
- State Changes - Changing between solid, liquid and gas.
- Dissolving - When a solid is broken down into small pieces to become part of a liquid.
- Crystalisation - When a substance forms crystals causing it to become harder and more brittle.
- Magnetisation - When a material becomes magnetic or loses its magnetism.
